INOFFICIOUS, civil law. This word is frequently used with others; as, inofficious testament, inofficiosum testamentum; inofficious gift, donatio inofficiosa. An inofficious testament is one not made according to the rules of piety; that is, one made by which the testator has unlawfully omitted or disinherited one of his heirs. Such a disposition is void by the Roman civil law. Dig. 5, 2, 5; see Code, 3, 29; Nov. 115; Ayl. Pand. 405; Civil Code of Lo. art. 3522, n. 21.
